sound proof sponge

The wavy material is full of tiny gaps, and the porous structure can absorb a large amount of incoming sound wave energy, thus attenuating the sound waves. The wavy sponge can also be compounded with rubber sheets to achieve better sound insulation and sound absorption effects.

Performance characteristics:

1) Good sound absorption

2) Good thermal insulation

3) Precise layout and stable shape

5) Light weight and convenient construction

6) Environmentally friendly, harmless to the human body, no pollution, no odor

7) Flame retardant HF1 grade

8) Composite PU sponge + rubber sheet to achieve better results
